UMBRIATICO. - One of the five microscopic dioceses that formed the metropolis of S. Severina (v.) in Calabria.
It was erected by the Byzantines in the 9th century and must certainly be identified with the Εὐράνων of the Notitia III or Dastiposi of Leo VI the Philosopher, which Grimaldi mistakenly identified with Uria or Miria near the Simeri river and Minasi even with Oria in Apulia. A Greek document from 1164, published by Holtzman (in Byzant. Zeitschr., 26 [1926], p. 341 ff.), removes any doubt, because in it Robert, bishop of U., signs as ἐπίσωστος Εὐράς. The existence of a bishop of U. ordained by Hilary, archbishop of Reggio, at the time of Sixtus III, that is, in the 5th century, asserted by Ughelli and also accepted by Gams, is purely fantastic. Before the 8th century, metropolitans did not exist in Calabria, and U. was elevated to a diocese by the Byzantines along with the metropolis of S. Severina. Among the five tiny suffragans of this metropolis, U. had the largest extent and included within its territory the town of Corò, which was the birthplace of Luigi Giglio, the originator of the Gregorian calendar reform. In 1818 it was suppressed and its territory annexed to that of Cariati, which in turn had succeeded Cerenzia.
